ADJUSTABLE DEAD-COLLAR FOR d70@DWORKIhl'G-SHAPERSi.

Application led November' 17, 191]..

TO'QZZ tti/0m t may concern Be it known that l, HARVEY Gr. EooLns'roN, a citizen of the United States of America, residing at fonia, in the county of Ilenia` and State of llitichigan, have invented certain new and useful Improvements in Adjustable Dead-Collars for Vvoodworking- Shapers; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in adjustable collars for wood working Shapers and its object is to provide a device which may be easily attached to the ordinary wood working shaper without any alteration of the said shaper, to provide a device simple in construction and effective in operation and to provide the device with various other new and useful features hereinafter more fully described and particularly pointed out in the claim.

lt is customary in shaping irregular outlined pieces of mat-erial on a wood working shaper, to provide a pattern the edge of which conforms to the desired outline of the material to be shaped and to provide means for clamping the material to the pattern andy it has been customary to run the edge of the pattern in contact with the running collars on the shaper spindle to guide the material against the knives. This is objectionable for that the friction of the pattern against the running collar soon destroys the pattern and also retards the rotation of the spindle. En a good many cases the rotating collar is not fixed absolutely true on the spindle and in rotating against the pattern will vibrate the same thus producing rough work.

lt is the object of this invention to overcome these objections by providing stationary collars to surround the rotating collars on the spindle against which the edge of the pattern is moved to guide the work and means for holding and adjusting these nonrotating collars as will more fully appear by reference to the accompanying drawings, in which Figure 1 is a perspective view of a portion of the shaper table showing my newly invented dead collar device in operative Specification of Letters Patent.

position and illustrating one form of pattern: Fig. 2 is a plan view of the device; Fig. 3 is a side elevation of the same; and Fig. 4 an end view.

Like numbers refer to like parts in all of the figures.

l represents the shaper spindle.

2 is the pattern in which the work to be shaped is clamped the edge 2a of which has the desired form of the work to be shaped and engages the stationary collars to guide the work.

8 is a post rigidly supported in one end of a bed plate lsecured to the table of the shaper, cap screws 8 being shown for that purpose. To the other end of this bed plate is secured a lower stationary collar o which surrounds the spindle below the knives and close to the table of the shaper.

6 is an arm arranged parallel with the bed plate carried by the post 3 and vertically adjustable thereon, to space apart the collars to conform to the various widths of knives that may be used on the spindle. rThis arm 6 is preferably splined to the post as at 9 to maintain it parallel with the bed plate l and has a collar 7 fixed to its outer end directly above the collar 5. These two collars are non-rotative and concentric with the shaper spindle which rotates freely within them. A set screw l0 maintains the vupper arm in adjustment on the post.

For work of considerable width it is sometimes desirable to use a double pattern and both collars as illustrated in the drawings but obviously either one or the other of the collars may be used if preferred with a single pattern.

The operation of the machine is substantiallythe same as an ordinary shaper except that the collar is moved in contact with the non-rotating collars 5 and 7 and thus avoids the objections mentioned.

By the use of my device the patterns are not injured in any way and there is no frictional resistance to the rotation of the spindle. rEhe user is also able to work much more rapidly as the pattern edge always engaOes a rigid smooth surface and smooth work will always result without any particular skill or painstaking on the part of the operator.
